In 9/1973 I was riding in NE Utah, over the (then very narrow) 2-lane mountain pass eastbound toward Big Bear Lake, with my ex. It was about 7 PM, almost sunset when we came to the crest of the pass. I looked up and saw the air horns of a big rig 'rising' on the other side of the crest and then, all of a sudden, a "movie" flashed across my mind: I saw a light green Dodge Dart (1970s style) coming at me in my lane, trying to pass the semi into the sun, over that crest. About that time I could see the truck driver, who's eyes were WIDE open, as he pulled the [old] air horn chain to honk, and then I saw the roof of the green Dart rising over the same crest, in my lane. I whipped over to the right edge of my lane where a white line was on the edge of the blacktop, and I rode right on it: about 1 foot further to the right was a 150-foot or more dropoff, almost no shoulder to the road there. My ex started screaming at me and was beating me on my back (she hated heights) as the Dart passed by about 6"-8" from my left knee, she never even saw it. The truck was still on his horn as he passed me and I whipped back into the center of my lane. Until we split, she never believed me, why I rode that 4" wide white line on the edge of a cliff that day - probably still doesn't. She's like that...
